Liquitex Professional Fluid Medium Acrylic Gloss 118 ml — Increases Transparency & Flow

This fluid medium from Liquitex is formulated to alter the handling and finish of acrylic paints without adding heavy body or visible brushstrokes. Designed to thin heavier acrylics, boost colour depth, and create a permanent gloss surface, it stays flexible when dry and resists dirt retention. The product is translucent when wet and clear once cured, and it’s compatible with a wide range of substrates except oil-painted surfaces.

How does Liquitex Fluid Medium change paint behavior?

When mixed with acrylic paint, this fluid medium reduces viscosity and promotes self-leveling, which softens brush marks and allows smoother application. It also increases transparency and colour depth, so glazes and washes appear more luminous. The medium retains adhesion and durability through added acrylic resin in the formula.

• Reduce viscosity of heavy-body paints for pour techniques or smooth blends
• Increase colour intensity and transparency for glazing
• Maintain adhesion and film flexibility across substrates

Can I use it as a varnish or topcoat?

Yes — Liquitex Fluid Medium (Gloss) can be applied as a permanent, non-removable varnish over fully dry acrylic paintings. It creates a hard, flexible gloss finish that helps repel dirt and evens out sheen. For a lighter gloss or thinner application, it can be diluted with distilled water in controlled ratios.

• Use undiluted as a final permanent gloss varnish on dry acrylics
• Mix 1 part Gloss Medium with 1 part distilled water for a lighter finish
• Apply in a clean, dust-free environment to avoid trapped particles

Which surfaces and techniques is this medium best suited for?

The formula bonds to both flexible and rigid surfaces including canvas, paper, wood, and Plexiglas, making it versatile for mixed-media and traditional acrylic work. It’s suitable for extending paints, glazing, pouring, and creating smooth leveling layers. Avoid using it over oil-based paints—adhesion and curing are optimised for acrylic systems.

• Ideal for canvas, paper, wood, Plexiglas and other acrylic-compatible surfaces
• Great for extending paint volume, glazing, and pour-style effects
• Not recommended over oil paint; designed for acrylic applications

Who is this for: Artists, students, and professional makers who want a reliable gloss medium to manipulate acrylic paint flow, build transparent layers, or add a protective sheen will find this Liquitex fluid medium useful. It’s also appropriate for educators and workshop settings because it meets ASTM D4236 and dries to a stable, non-tacky finish. Choose the 118 ml (4-oz) bottle for a convenient studio size that’s easy to store and use in both small projects and testing techniques before scaling up.
